Just wondering - how much bandwidth do you need?

If you are going to run with a fixed amount of decimation for all of
your tests, you can change the FPGA's CIC to have a fixed value and
bypass the halfband filter if you want.  This will free up a
SIGNIFICANT amount of space in the FPGA to perform filtering,
equalization, and other processing.

The default build allows for some serious decimation, and a LOT of
options for general SDR.  For more specific purposes, use the sdr_lib
to your advantage, make your custom chain, and write the rest of your
custom FPGA load.

I am no expert, but I believe the USRP samples 4 real or 2 complex
channels at 64MHz.  Is there reason to believe this is not enough
bandwidth?
